摘要：

Epitaxial Fe50Pt50 (30 nm) magnetic thin films were sputter-deposited on Cu (001) single crystal substrate. The fct L1(0) ordered FePt (200)<001>parallel toCu (002)<100> epitaxial relationship was observed using high-resolution x-ray scattering. The L1(0) ordered FePt film sputtered at 400 degreesC with well-controlled easy-axis distribution (full width at half-maximum=2.36degrees), small grain size (10 nm), and high in-plane coercivity (4.4 kOe) is a potential candidate for ultrahigh-density longitudinal magnetic recording media.
